Espresso Craft: Dialing In and Pouring, a free food & drink course on Tomo

Espresso Craft: Dialing In and Pouring

Move beyond button-pressing into precise extraction control and fluid dynamics. Learn to dial in coffee by taste, fix channeling under pressure, and texture silky microfoam for consistent pours.

Like Duolingo, but for Espresso Craft: Dialing In and Pouring. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 10 levels across 2 sections, about 20 minutes end to end, roughly 4 days at five minutes a day. It moves through Dialing In and Extraction Physics and Texture, Integration, and Workflow. It assumes you already know the basics.

Key ideas in Espresso Craft: Dialing In and Pouring

  • Brew ratio dictates espresso concentration and body by altering total liquid yield
  • Pulling more yield dilutes concentration, creating a lighter body and softer balance
  • Chasing a rigid shot time without changing yield will not alter beverage ratio
  • Underextraction tastes sour and salty because sugars were not dissolved in time
  • Overextraction leaves an astringent, drying mouthfeel with harsh bitterness
  • Balanced espresso extracts enough sweet carbohydrates to buffer bright organic acids
  • Locking dry dose weight isolates water flow resistance to grind size alone
  • Changing dose and grind together creates two moving targets in puck resistance
  • A constant basket headspace ensures consistent mechanical puck compression
  • Shot time acts as a speedometer to check water flow resistance through the puck
  • Taste on the palate always overrides the target extraction clock
  • Choosing brew ratio over shot time to shift drink body and flavor balance
  • Some coffees extract cleanly and evenly at faster flow rates without channeling
  • Highly soluble organic acids and salts extract first in the opening seconds
  • Middle extraction pulls sweet solubles and lipids that build sweetness and body
  • Heavy plant compounds extract last, introducing astringency and bitter tannins
